To answer these questions, we need to understand the concept of loan amortization and how extra payments affect the loan.<br /><br />a. The extra one-time payment of $100 reduces the total interest Janet pays on the loan. This is because the extra payment goes towards the principal balance, which in turn reduces the amount of interest that accrues on the loan.<br /><br />b. The impact on the number of months it will take Janet to pay off her loan is that it will be reduced. This is because the extra payment helps to pay down the principal balance faster, which means that there will be less interest that accrues over time.<br /><br />7. If Janet had been making $285.05 payments for the entire duration of the loan, the impact on the total interest she would have paid would be that it would be lower. This is because the extra payment would have been applied to the principal balance more frequently, which would have reduced the amount of interest that accrues over time.<br /><br />b. The impact on the number of months to pay off the loan would be that it would be reduced. This is because the extra payment would have helped to pay down the principal balance faster, which means that there would be less interest that accrues over time.<br /><br />8. If Janet's pay-off goal was 4 years (48 months) instead of 2 (24 months), her new monthly payment would be higher. This is because the longer the loan term, the more interest will accrue over time, which means that a higher monthly payment would be required to pay off the loan in a shorter period of time.
